Dev Builds » 20230218-1223

You are viewing an old NCM Stockfish dev build test. You may find the most recent dev build tests using Stockfish 15 as the baseline here.

Use this dev build

NCM plays each Stockfish dev build 20,000 times against Stockfish 7. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

Fix overflow in add_dpbusd_epi32x2 This patch fixes 16bit overflow in _add_dpbusd_epi32x2 functions, that can be triggered in rare cases depending on the NNUE weights. While the code leads to some slowdown on affected architectures (most notably avx2), the fix is simpler than some of the other options discussed in https://github.com/official-stockfish/Stockfish/pull/4394 Code suggested by Sopel97.
